Application led July 5, 1923. Serial No. 649,588.

` This invention relates to vehicle doors and Vthe like, and has for one object to provide Van improved hoisting mechanism for a window or door sash, being particularly adapted for raising and'lowering the sash or window glass for the doors of closed vehicle bodies. p

A further object of. the invention is to economize in 'the construction ot the hoisting mechanism by making all or the greater por- -tion of the parts in the form of stampings, and wherever possible, connecting them with the lock boardby means ot portions integral either withtheparts themselves, or with the lock board. l Y.

To these andother ends, the invention embodies certain novel features ot construction and arrangement ot parts, as willv be hereinafter more v'fully pointed out and claimed, it being understood that the invention is susceptible ot various modifications, embodiments and arrangements to suit special or varying conditions under whichthe invention may be practiced.k l

YAstructure constituting one embodiment K ofthe invention, is illustratedY in the accompanying drawings, in'which: Y

`Like reference characters illustrate corresponding parts throughout the several views e5 ot the drawings.

In illustrating the present invention, I have preferably shown it applied to avehicle door 1 0, including stiles 11 connected by theupper and lower rails 12 land 13 respectively, andalso the Oppositely spaced intermediate rail members 14 and 15, as shown in Fig. ILrall adapted to be connected inanyk desired manner. The sash or window glass 16 is suitably mounted for vertical movement inthe door trame, preferably between the inner and outer vertically disposed moldings or finishing strips v17, connected by similar top and bottom transverse moldings 18 and 19,V as shown in Fig. I.

The panel or lock board 20 is-preferably formed of stamped metal and is connected with the upright door frame members 11, as by means of the screws 21. The panel is provided along its upper edge with an outwardly turned flange 22 upon which rests the cross frame member 15 of the door, and to which the flange' is suitably secured as by means of screws, (not shown).

@ne of the important features of the invention, is the mounting of all parts of the window hoisting mechanism upon the panel or lock board, including also the handle for closing the door, and applying the completed unitary structure to the door frame, simply by placing it in position thereon and driving the screws :tor connecting it therewith. In carrying out this idea, ,a bracket 23 is provided with a central portion spaced from the panel and a flanged portion 23 suitably, connected therewith, as by means of the rivets 24, or in any other desired manner.Y Annular hanged portions 25 and 26 are provided on the Vpanel and bracket respectively, which form spacedy bearings in which the hollow rotatable shaft or actuating member 27 of the hoist-ingk mechanism is rotatably mounted. The actuating membercarries a gear 28, prei'- erably a stamping, which is operatively connected with the actuating member by means of a pin 29 extending through oppositely positioned slots 30 formed therein, whereby said actuating member is permitted to rotate a limited amount before it moves into driving engagement with the pin 29 of the gear28. The gear 28 is adapted to mesh with and operate a segment 31,l mountedon a pivot32 near the bottomof the panel. An arm or lever 33 for lifting the sash is rigidly secured to the segment in any desired manner, as by Vspot-welding, and is also connected therewith by means of the pivot pin 32. The lever 33 carries a grooved roller 35, upon which rests the rounded edge of the sash channel 36 as shown in Fig. H. At this point, the sash carries a i longitudinally extending guard plate 37 formaintaining the roller-in supporting engagement with the sash, upon whichpit is adapted to travel when the lever is raised and lowered by the segment to elevate and lower the sash. A counter-balancing spring 38 isconnected ationeend with an outwardly bent portion 39 ofthe segment,

and at the other end with a downwardly bent lipry40., preferably integral with the flange 22 of the door board and having a series O ap,V

ertures'41, in anyone ot which the end of the spring may be secured, depending upon.v the.V

Y tension required to properly balance the sash.

Therotatable actuatingV member 27 is provided with a crank handle42, which is nonrotatablel relative to the actuating member,

and which is held against' longitudinal move:

ment'thereon'by a set-screw 48. The actuating member is provided with "oppositelyposii tioned longitudinal slots 44 adapted to receive correspondingly disposedv ribs` 45, vpreferablyv cast integralwith the crank handle on `the inner Wall ofthe socket portionthereot, in

Vwhich the endot the actuating vmember is disposed, thus affording a drivingv connection between ithe lhandle and actuating `member land relieving the strain on the set-screw 43. n TheV means for automatically locking theV hoisting mechanism Whenever rotation of the 25 crankA handlev is discontinued, Vcomprises a gear 46, or its equivalent, normallyheld againstl rotation by any suitable stop, Vsuch as the "rack 47`riveted or otherwise lsecured to the inner face of the bracket 23. The gear is automatically returned to locking engagementfwith'the rack or stop by a spring 48 l 'f interposed between 'said gear and the'gear 28 for actuating the segment 31. Itis necessary .I ,y of course upon initial rotation ofthecranlr handle and 'before rota-tionof the actuating V ,f fear'28g`A is b egumto Vlirst release the. locking Amechanism'.` For this purpose, the gear'46,

' hasv a driving pin y49. extending through the flanged hub portion -thereof and through the oppositely positioned cam grooves or slots in the actuating member 27, the slots having cam faces 51 in contact with the driving pin 49. Consequently, upon rotation kofthe` actu-j atingmember in either direction, the cam A faces 5l'willslide the locking gear V46 to the right,1as viewed in Fig. lLithus moving it out jot locking engagement with the stop or rack-47. Y At about this time, thev actuating member 27 Awill have beenV rotated to the limit of Vits movementY before contacting with the pin 29m thelslot 30 thereof, and upon engaging the pin, rotation of the gear 28 wilhbegin,

desired elevation.4

thereby eltecting' movement of the sasheither up or down, depending upon the direction in which the Vcrank handle isturned.'V Asisoon as rotationof the handle is discontinued, the spring 48 will automaticallyjslide the gear o r locking member 46 back into .engagement with the rack 47,thiis holdingY the sash at the It, found desirable, one or more idler gears (not shown), may be interposed between theV driving gear 28 and thescgment 3l, thus per- `mitting the actuating member V27. andv the crank handlethereon to belocated themost desirable position convenient for the occupant of the vehicle. n y

While the construction herein shown and described is well adapted .to fulfillthe objects primarily stated, vit is `tobe understood that changes in the form, proportions, arrange- Vmentor' parts and details of construction, may be resorted `to when found expedient, Without departing rom'the spirit of the invention as .expressed in the claims. l l .Y
